I'm not up on what's available in the stores today but I'd like to suggest a shingling axe if it's primary use will be splitting smaller size chunks down into chips. I'd also suggest checking out ebay for a vintage model, you can score them very cheap because there's just about no use for them anymore in today's world. The trick is that they're not called shingling axes on ebay because people don't know the correct name so you have to search axe or hatchet and look at the pictures.
